WARNINGS, CAUTIONS, AND NOTES
WARNING:
Navigation and terrain separation must NOT be predicated upon the use of the terrain function.
The G1000 Terrain Proximity feature is NOT intended to be used as a primary reference for terrain avoidance
and does not relieve the pilot from the responsibility of being aware of surroundings during flight. The
Terrain Proximity feature is only to be used as an aid for terrain avoidance and is not certified for use
in applications requiring a certified terrain awareness system. Terrain data is obtained from third party
sources. Garmin is not able to independently verify the accuracy of the terrain data.
WARNING:
The displayed minimum safe altitudes (MSAs) are only advisory in nature and should not be
relied upon as the sole source of obstacle and terrain avoidance information. Always refer to current
aeronautical charts for appropriate minimum clearance altitudes.
WARNING:
The Garmin G1000, as installed in the Mooney M20M/M20R/M20TN, has a very high degree of
functional integrity. However, the pilot must recognize that providing monitoring and/or self-test capability
for all conceivable system failures is not practical. Although unlikely, it may be possible for erroneous
operation to occur without a fault indication shown by the G1000. It is thus the responsibility of the pilot
to detect such an occurrence by means of cross-checking with all redundant or correlated information
available in the cockpit.
WARNING:
For safety reasons, G1000 operational procedures must be learned on the ground.
WARNING:
The altitude calculated by G1000 GPS receivers is geometric height above Mean Sea Level and
could vary significantly from the altitude displayed by pressure altimeters, such as the GDC 74A Air Data
Computer, or other altimeters in aircraft. GPS altitude should never be used for vertical navigation. Always
use pressure altitude displayed by the G1000 PFD or other pressure altimeters in aircraft.
WARNING:
The Jeppesen database used in the G1000 system must be updated regularly in order to ensure
that its information remains current. Updates are released every 28 days. A database information packet is
included in the G1000 package. Pilots using an outdated database do so entirely at their own risk.
WARNING:
The basemap (land and water data) must not be used for navigation, but rather only for non-
navigational situational awareness. Any basemap indication should be compared with other navigation
sources.
CAUTION:
The illustrations in this guide are only examples. Never use the G1000 to attempt to penetrate
a thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms, and the Airman’s Information
Manual (AIM) recommend avoiding “by at least 20 miles any thunderstorm identified as severe or giving an
intense radar echo.”
